control of the while spotted beetle

[John85]

How do you control oxythyrea funesta  without killing the bees and other beneficial insects?A Hungarian study shows that you can add a chemical to the traps to make them more attractive (kind of lavander oil).Can somebody translate that into a brand name?Or may be you know another bee friendly way?

Happily  I am not at all familiar with these White-spotted Rose Beetles (Oxythyrea funesta)
I had to go looking to see if I recognised it.....  http://www.zin.ru/animalia/coleoptera/eng/oxyfunpo.htm

 I'm not sure how widespread they are in the UK or even if they are present here. Seems they can make quite a nuisance of themesleves on many plants..... so, if this lavendar oil suggestion has any merit it might also be applicable to other deterrents for other pests. Does no-one out there have experience of this beetle and how to treat it without harming the benficial insects?
